Question

Given are the standard oxidation potentials;
Fe = 0.44 V; $C{l}^{\ominus }=-1.36V$

Assertion: The cell; $Fe+C{l}_2\left(g\right)\to F{e}^{2+}+2C{l}^{\ominus }$ is spontaneous.

Reason: $E_{cell}^{\ominus }$ is negative.

• A. Both Assertion and Reason are true but Reason is not the correct explanation of Assertion
• B. Assertion is true but Reason is false
• C. Assertion is false but Reason is true
• D. Both Assertion and Reason are false
• E. Both Assertion and Reason are true and Reason is the correct explanation of Assertion
  

Answer 1

Answer: (B)

$\to$ For a reaction to be spontaneous

$△G=-ve$

means $E_{cell}=+ve$

Since $△G=-nF{E}_{cell}$
